Substantive interoperability between Live, Virtual, and Constructive (LVC) assets is essential to providing the highest quality warfighter training. However, the current LVC architectures in common use are not interoperable. The High Level Architecture (HLA) is most often used in the M&S community for integrating virtual and constructive assets, while the Test and Training Enabling Architecture (TENA) is widely used to integrate live assets into training exercises. We will discuss both technical and substantive interoperability issues between the architectures.

This paper will propose a strategy for moving toward improved LVC interoperability, and will focus on one aspect of interoperability… namely Object Model interoperability. The paper will explore the feasibility of using the Base Object Model (BOM) as a foundation for bridging the significant deficiencies that exist in the integration of HLA Federation Object Models (FOMs) and TENA Logical Range Object Models (LROMs). Inconsistent object models are a major source of interoperability problems. This paper will cover some of the more common interoperability problems as well as proposing solutions supported by a well designed BOM.
